I was on a dyno 2 weeks ago, now if i get a TMIC do I need another tune? So far Grimmspeed j-pipe/ borla catback and the cobb big sf. Stage 2+ and Running redline 5w40, for winter goin resline 5w30. Any advice on a "next mod"? Thinkin intercooler (process west).
If you'd like to take the path of others, TGV deletes and an EBCS would be a good next step. Nice numbers.
Also, as far as oil is concerned, you'd be fine to stick with the 5w40 for winter as well. The end number is the warm weight. If anything, you'd switch to 0w40 for winter so you're that much farther from pumping glue on startup.
